RZ 2.5Rotary vane pump

Overview

  • high flow rates even at vacuum levels approaching ultimate vacuum
  • very good ultimate vacuum even with gas ballast
  • vacuum-tight at switch-off; external anti-suckback valve not needed
  • large oil volume: Long intervals between oil changes
  • ease of maintenance due to telescopic design

Ultimate vacuum

2 x 10-3 mbar

Ultimate vacuum with gas ballast

1 x 10-2 mbar

Max. pumping speed 50 Hz

Rotary vane pump in action

The one-stage RE 2.5 and two-stage RZ 2.5 are high-performance rotary vane pumps with extra compact design and low weight. They are the ideal solution for a wide range of laboratory and process applications that require low ultimate vacuum at medium gas flow rate. The RZ 2.5 is also available combined with the oil mist filter (FO) and the VS 16 valve as a package. Typical applications are lyophilization, fine vacuum distillation and evacuation of small volumes, e.g., for utilization of µ-focus x-ray tubes or filling with pure gases.
